I guess scientists showed volunteers a series of facial images and they were able to record the brain's response to the different features like smiles or skin color and using that information they were able to re-create the images based only on the brain's response. If you're dreaming after you've been through this they can display the image of what your brain is scanning up on a screen. Wow. Crazy. That is. Would you want to do that? What's the benefit?
